The most promising candidates for energy storage capacitor application are relaxor ferroelectrics, among which, the perovskite structure ferroelectric ceramics have witnessed great development progress. However, less attention has been paid on tetragonal tungsten bronze (TTBS) because of their lower breakdown strength and polarization. Herein, a multiscale regulation strategy is proposed to tune performances (ESP) TTBS from grain, domain, macroscopic scale. enhanced behavior with dynamic...
Abstract With the gradual promotion of new energy technologies, there is a growing demand for capacitors with high storage density, operating temperature, voltage, and good temperature stability. In recent years, researchers have been devoted to improving properties lead‐based, titanium‐based, iron‐based multilayer ceramic (MLCCs). However, limited research has conducted into MLCC development using NaNbO 3 (NN)‐based materials. this paper, successful achievement excellent overall performance...
Abstract Dielectric ceramic capacitors with ultrahigh power densities are fundamental to modern electrical devices. Nonetheless, the poor energy density confined low breakdown strength is a long-standing bottleneck in developing desirable dielectric materials for practical applications. In this instance, we present high-entropy tungsten bronze-type relaxor ferroelectric achieved through an equimolar-ratio element design, which realizes giant recoverable of 11.0 J·cm −3 and high efficiency...
Dielectric materials with high energy density have attracted much attention due to their potential applications in modern electronics and electrical power systems. In this work, a large storage of 3.2 J/cm3 was achieved La/Mn codoped AgNbO3 antiferroelectric ceramics through enhancing the ferroelectric-antiferroelectric backward transition field reducing remnant polarization simultaneously. Moreover, coexistence Mn2+/Mn3+ at A-site disrupts randomly disordered Nb5+ temperature, leading...
Abstract Tooth whitening has recently become one of the most popular aesthetic dentistry procedures. Beyond classic hydrogen peroxide-based agents, photo-catalysts and piezo-catalysts have been demonstrated for non-destructive on-demand tooth whitening. However, their usage challenged due to relatively limited physical stimuli light irradiation ultrasonic mechanical vibration. To address this challenge, we report here a convenient strategy based on pyro-catalysis effect, realized via...
